MATLAB running on Mac OS after closing laptop?

So I have a code that by my estimation, should take about 4 hours to run to completion. I had to go somewhere while the code was running and closed my laptop but didn't kill the code.

I was surprised when I just opened my laptop back up and saw that the code was still running (the code constantly prints output, in the form of something like "number of iterations to converge: __" but after a while under normal circumstances, that number stagnates to around 2, so I'm not sure if it's just caught in a loop of spewing the same output as when I closed it, or if it's actually running).

I'm not sure if this is a glitch and I should just kill the program and restart, or if it's actually still running and I should just let it do it's thing.

Anyone have some insight?

I am having the exact same issue.
